Google is one of, if not the, biggest player in terms of information served over the internet. If they are willing to censor at this level, how far will they go to protect their public image and suppress discussion they don't agree with?
Any more than I "censor" you if you come on to my property and refer to my daughter as the "c"-word. I mean... you can call my daughter whatever you like, I just don't allow you to do it in my house. That's not really censorship no matter how big the house is, that's just something that people should expect to happen. In fact... I think people should find it more strange if my daughter and I did NOT put you out of our house.
You can still call her whatever you like outside of our home. You're still free to do that.
I'm not saying you don't have the right to do that, or that in this example your son was right, I just think it would be an over-reaction and would create a chilling effect on your other children from asking questions or thinking about things differently.
Recall that the employee that was fired is an adult (and apparently in his 30s, at least).
Also yeah he had to bei in his 30th how else would he have gotten his phd? But like I said the age wasn't the point.
Worth noting: he could post this publicly on Google+, Blogspot, or any other Google platform. It's only his paycheck that's being suppressed, his views are not.
Make no mistake, it's his views that he was fired over, not the medium in which he shared them. Google made no indication otherwise.
